"No module named 'pydens.batchflow' " about pydens HOT 9 CLOSED

I'm using Spyder3 to run this code:

`
import pydens as pde
from pydens import D
import numpy as np
import tensorflow as tf

pde.add_tokens()

pde = {'n_dims': 2,
'form': lambda u, x, y: D(D(u, x), x) + D(D(u, y), y) - 5 * pde.sin(np.pi * (x + y)),
'boundary_condition': 1}

body = {'layout': 'fa fa fa f', #estrutura da rede neural (layers)
'units': [15, 25, 15, 1], #neurônios por camada
'activation': [tf.nn.tanh, tf.nn.tanh, tf.nn.tanh]} #ativação advinda do TFlow

config = {'body': body,
'pde': pde}

us = pde.NumpySampler('uniform', dim=2)

dg = pde.Solver(config)
dg.fit(batch_size=100, sampler=us, n_iters=1500)
`
...and I'm getting this error:

`File "C:\Users\my_user\Anaconda3\lib\site-packages\pydens\letters.py", line 20, in
from .batchflow.models.tf.layers import conv_block

ModuleNotFoundError: No module named 'pydens.batchflow'`

My tersorflow are actualized and I got PyDEns and Batchflow with pip on conda terminal.

Do Tensorflow have to be version 1.14??

Hey, @adsmendesdaniel!

First of all, thanks for the interest!

It looks like installation from PyPI doesn't work: clearly, we've forgotten to upload batchflow-submodule on the repository. We'll fix this as soon as possible! As of now, you can install pydens using

pip3 install git+https://github.com/analysiscenter/pydens.git

This command will automatically include the needed batchflow-submodule.

As to your second question: pydens should work just fine with tensorflow 1.8 and higher.

Best,
Alex

Sorry, I installed pydens with pip and anaconda git, but I'm still getting the problem...

from pydens.

That looks strange. Did you try to uninstall the previous version of pydens before reinstalling it using pip + git?

pip uninstall pydens

If uninstalling doesn't help, I'd suggest you to use

git clone --recursive https://github.com/analysiscenter/pydens.git

for the installation of pydens into a specific folder.

It worked!! Probably it wasn't running because I didn't uninstall the previous version.
Thank you.

Well, I have a problem even with the initial things like installing and then the current error that has been posted on this page. I do not know how to install using "git" since the windows does not accept installing though that command. Of course,

I have added in my variable environment the new paths but still, I am suffering from that.

Hello,

you should probably try to install git by using this

Dear ,
thanks for your prompt reply. I did it at the time but I faced the issue of this page "No module named 'pydens.batchflow'" and I followed the steps of the page but nothing changed and happened.

Try to completely uninstall everything and run git clone --recursive https://github.com/analysiscenter/pydens.git, as it seems that batchflow submodule was not correctly pulled
